I need help, please!

My vario recently "jammed", or something. Basically, here's what happened: a couple of weeks ago when I tried grinding coffee as usual the Vario "clicked" (as in, you could hear a clicking sound from it, like a switch flipping), the countdown on my timer began, but nothing happened.

I took the top burr out and cleaned everything, replaced it in the chamber, and everything was hunky-dory. Today, while grinding, the machine started to "stutter" before stopping. Again, pressing the start button results in "click" and countdown but no grinding.

This time I took both top and bottom burrs out, cleaned both and the chute.
Replaced burrs. Started it empty on the coarsest setting, moved up to finer setting. Calibrated it so that at the finest setting the burr labours a bit.
I put it back down to the coarsest setting and added my coffee. Then I started grinding and moved the setting up to the what looked to me near a fine enough grind for espresso and I ground 4-5 grams of coffee at the setting.

Everything was fine.
I turned my machine on to warm up.
When the PF and all was up to temp, the Vario would not grind again!

=( Any ideas what's going on before withdrawal symptoms start kicking in?

Your best course is to call Baratza. Their support in solving issues like this is stellar.

I agree with Hal. For reference, the problem above sounds similar to the one described in Baratza Vario death by single stone; he ended up replacing the pulley and belt.

Thanks guys. I was trying to avoid needing to contact them and do it on my own hoping it'd be a quick fix but ended up speaking with Kyle and Pierce at Baratza per your suggestion.

Despite repeatedly hearing (reading) how great their support is, I could not anticipate just how phenomenal and processive they are in fact. They certainly deserve their astounding reputation. (And I have more faith in their product than ever too.)

They'll be sending me a replacement face and power board, as the belt/pulley looked fine when I opened the machine up.

I have the same issue every so often. I find that doing the course to fine movement while grinding seems to solve the problem.
